查看cs状态：发现是有问题的

[root@master1 ~]#kubectl get cs
Warning: v1 ComponentStatus is deprecated in v1.19+
NAME                 STATUS      MESSAGE                                                                                       ERROR

scheduler            Unhealthy   Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection refused   
etcd-0               Healthy     {"health":"true"}

解决思路： 注释掉/etc/kubernetes/manifests下的kube-controller-manager.yaml和kube-scheduler.yaml的- – port=0 确认kube-scheduler和kube-controller-manager组件配置是否禁用了非安全端口

[root@master1 ~]#cd /etc/kubernetes/manifests
[root@master1 /etc/kubernetes/manifests]#ls
etcd.yaml  kube-apiserver.yaml  kube-controller-manager.yaml  kube-scheduler.yaml
#搜索- – port=0更改为：#- – port=0
[root@master1 /etc/kubernetes/manifests]#vim kube-controller-manager.yaml 
[root@master1 /etc/kubernetes/manifests]#vim kube-scheduler.yaml

重启kubelet：

sudo systemctl restart kubelet

查看端口是否开启：10251和10252

[root@k8s-master ~]# netstat -tunlp | grep 10251
tcp6       0      0 :::10251                :::*                    LISTEN      16049/kube-schedule 
[root@k8s-master ~]# netstat -tunlp | grep 10252
tcp6       0      0 :::10252                :::*                    LISTEN      16050/kube-controll

重启服务之后确认组件状态，显示就正常了

[root@master1 /etc/kubernetes/manifests]#kubectl get cs
Warning: v1 ComponentStatus is deprecated in v1.19+
NAME                 STATUS    MESSAGE             ERROR
scheduler            Healthy   ok                  
controller-manager   Healthy   ok                  
etcd-0               Healthy   {"health":"true"}
